情境例句
辦公室設備安裝

詞族
cord noun 電線；連接線・corded adjective 有線的；需接電線的・cordless adjective 無線的；使用時免接電線的
四選一
The technician's drill is ____, so it can operate without a power cord attached.
看答案
cordless
後半句說明電鑽不接電源線也能運轉，因此選 cordless。corded 雖是形容詞，但意思與後半句矛盾；cord 是單數可數名詞，此處缺限定詞且語意不合；cords 是複數名詞，也不能合理描述這支電鑽。
同義改寫
The technician used a cordless drill to install the shelves in the meeting room. → The technician used a drill that operates without a power cord to install the shelves in the meeting room.
以 operates without a power cord 展開 cordless，保留電鑽運轉時免接電源線的意思。
The receptionist carried the cordless phone into the storeroom while checking the supplies. → The receptionist carried the phone whose handset connects to its base without a cord into the storeroom while checking the supplies.
此處 cordless phone 指話筒與底座之間不接線的電話；改寫保留此特性，未將它改成手機。
